What is the function of the external carotid arteries?

Answer 19

the external carotid arteries are responsible for supplying blood to most of external structures of the head and the orbits

Question 20

Describe what would happen if the blood supplied to the brain was impeded for even just a few minutes.

Answer 20

since blood supply to the brain for just a few minutes can cause sever damage to brain tissue

another name for the cerebral arterial circle is “the circle of willis”

Question 22

Describe the structure and function of the cerebral arterial circle (circle of willis)?

Answer 22

the cerebral arterial circle is a ring of blood vessels formed by three anastomoses that supply oxygenated blood to brain tissue
